SPRING-BED.

SPECIFICATION forming part of Letters Patent No. 240,919, dated May 3,1881.

Application filed July 26, 1880.

To all whom it may concern:

Be it known that I, FRANK B. MIX, of Decatur, in the county of Macon andState of Illinois, have invented certain new and useful Improvements inSpring-Beds; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being bad to the accompan yin gdrawings, and to letters ofreference marked thereon, which form a part of this specification.

.My invention relates to an improvement in spring-beds, and is designedto provide alight, simple, and cheap article, and one possessing manyadvantages over old forms, inasmuch as it is easily adjusted and adaptedto fit bedframes of any size and ordinary construction, and is readilyattached to or removed therefrom. Moreover, it is lasting in use, willnot wear or injure the bedding, and is capable of being taken apart andcompactly packed for transportation.

With these ends in View my invention consists in a spring-bed formed ofa series of double spiral springs having their laterally-proj ectingloops interlocked with each other, placed on the slats in the bed-framein rows, and made rigid by securing groups of four adjoining springstogether with an open link.

Myinvention further consists in certain details of construction andcombinations of parts, as will be hereinafter described, and pointed outin the claims.

In the accompanying drawings, Figure 1 is a plan of a bed provided withmy improved double spiral springs; and Fig. 2 is a perspective view,showing one of the double springs.

Arepresen ts one of my double spiral sprin gs, consisting of a singlepiece of wire coiled to form two spring-spirals, A A and provided with alaterally-projecting loop, B, by means of which a series of similarsprings are interlocked with each other to form a spring-bed. The wireends ca, projecting from the apex of the spirals, are adapted to bereceived into the sockets or holes 1) 1) formed in the transverse slatsS, constituting a part of the bed-frame, thereby insuring the springsfirm connection therewith and preventing them from displacement. Thespring A at the right-hand corner (No model.)

of the head-board E is secured thereto by a hook or eye screw, E,engaging with the end bar, 13, of the loop B of the spring, the wireends a a thereof being inserted in the sockets b b of the slats S, asbefore described. The next succeeding spring, B is interlocked with thespring A by inserting the end bar, 0, of its loop 0 beneath theuppercoils of the spirals of the spring A in such manner that the middleportion of said end bar, 0, will rest upon the top coil of said spirals.When a sufficient number of springs interlocked with each other, asdescribed, and forming a line or row, is ob tained to reach thefoot-board I ,they are thereto secured bya two-armed orbow-shaped hook,H, the arms d d of which respectively engage with the upper coils of thetwo spirals D D of the end spring, I, said hook being secured to thefoot-board by an eye-screw, hook e, or an equivalent therefor. Anydesired number of rows of springs, according to the size thereof and thewidth of the bed-frame, are thus secured therein. The springs of theadjoining rows are connected together, to give rigidity to thespring-bed, in groups of four springs each by an open link, L, (shown asconnecting the springs A, B C and D in the upper right-hand corner ofthe bed-frame,) the right-hand arm of the link L engaging with the uppercoil of the spiral A of spring 0 and the corner angle 0 of the loop ofspring D and tbeleft-hand arm of said link engaging with the upper coilof spiral M of the spring A and the corner angle 0 of theloop of thespring B AtNO P groups of four springs each arelikewise connected. It isthus, by means of one small open link, Iam enabled to secure foursprings and make the spring-bed rigid, and yet not in any way impair theelasticity thereof. Therows of springs are attached together, as aboveshown, except the two rows, which meet in the center of the bed. The twosides or sets of springs are thus separate,and act entirelyindependentof each other. My improved spring-bed is easily adj usted, and adaptedto fit bed-frames of any size and ordinary construction by adding to orremoving a row of springs from the side thereof, according as the bed istoo narrow or too broad, or adding to or removing springs from the endsof the rows, according as the bed is too short or too long. By freeingthe springs from the headboard and foot-board of the bed-frame, they maybe removed and compactly packed for transportation.

I would have it understood thatldonotlimit myself to the exactconstruction shown and described,buthold myself at liberty'to make suchslight changes and alterations as come within the spirit and scope of myinvention.

Having fully described my intention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a spring-bed, the combination of two or more double spiralsprings, each double spring being provided with a laterally-proj ectingloop, and the loop of one double spring being directly interlocked withthe coils of the two spirals of the adjacent double spring,substantially as set forth.

2. A spring-bed formed of double spiral springs, each provided withalaterally-project 2o ing loop, the end bar or portion of the loop ofone spring being inserted beneath and arranged to rest upon the uppercoils of the next adjacent spring, substantially as set forth.

3. In a spring-bed, the combination, with a 25 series of double spiralsprings, with their laterally- 'irojecting loops interlocked with thenext adjacent spring, of an open link arranged to engage with fouradjoining springs and give rigidity to the spring-bed, substantially asset 0
